Plants of Corchorus olitorius, a short-day plant, were subjected to varying numbers of short-day cycles before transfer to long days. Treatments started after germination of the seeds at the time of cotyledon release. Four short-day cycles (10 h natural daylight followed by 14 h darkness) were sufficient to induce flowering in all plants. The number of flowers and fruits produced on a plant increased as the number of short-day cycles was increased from three to 30. Plants given three to seven short-day cycles produced flowers on the main stem only but when plants were maintained in short days for longer periods, flowers were also produced on the branches. The growth in d. wt of fruits was greatest when plants were maintained in short days throughout.
